Do in-process/same appDomain Remoting TCP calls go via the network card?

.... or开发者_StackOverflow does .Net do something special if it determines the TCP call isn't necessary i.e. when the Remoting client and server are running in the same appDomain?

My guess is that if you're connecting to the loopback interface (127.0.01 or ::1) the calls will not get as far as the network card. If you're using an IP address assigned to the network card, I suspect the traffic will go through the network card (though whether the network card will make any shortcuts compared to actual traffic leaving the interface, I don't know).
